Answer:
all values stand for 3x+(-5)=19
- 3x-5=19=> 3x=24=> <u>x=8</u>.
Three step requires another step, so it is difficult than two step process.
no, their is no limit to the number of steps it take to solve an equation.
Every number can be described as a sum/difference of two or three numbers.

Answer:
Length = 17 cm
Width = 8 cm
Step-by-step explanation:
Let the length be x cm
Therefore, Width = (x - 9) cm
Perimeter of rectangle = 2(l +w)
50 = 2[x + (x - 9)]
50/2 = 2x - 9
25 = 2x - 9
25+ 9 = 2x
2x = 34
x = 34/2
x = 17 cm
x - 9 = 17 - 9 = 8 cm
Therefore,
Length = 17 cm
Width = 8 cm
Thus, the dimensions of the rectangle are 17 cm and 8 cm.
